Application filed September 5, 1911,

To ali? whom @'25 concern Be it known that l, .JOSEPH ANTONUCCIO, citizen ot the United States, residing at lFruitvale, in the county of Alameda and State of California, have invented a new and useful VVater-Heater,of which the following is a speciiication in' such full and clear A as to injure the wood-work adjacent the boiler.

Another object of the invention is to provide a heating dome which will have such a number of openings from one side of its shell to the other, as to deliver either hot water or steam as may be necessary.

The delivery of steam through the dome is accomplished by increasing the number of openings through the shell wherebyl more metal is exposed to the action of the heater.

Another advantage of this invention .lies in the possibility of delivering either stearh or hot'water from the heating drum as may be desired, by a change. in position and the number of openings through the shell of thel dome. For example, with aheating dome of a given size it is possible to increase the temperature of the water delivered therefrom very considerably by an increase in the number of openings through the dome, in which event, it sutlicient heat is used it is very easy to deliver steam from the heater. 1i' a heater such as is shown in Figure 4 is used, the openings will direct the iiame therethrough very readily, but the extent of metal in contact with the water is not`sul`licient to deliver steam as a product without unduly increasing the hea-t applied to the portion throughout the several views, Fig. 1 .is a side elevation partly in section of one form of the water heating dome. Fig. 2 is a side elevation partly in section of a similar water heating dome, showing the cold Water inlets thereto at the sides. F ig. 3 is a view part-ly in section of a boiler, and. the Water ?atented Nov. 4, 1913.

heating dome showing the relative position thereof. Fig. 4- is a sideelevation of a slightly modified form of water heating.

dome, and Fig, 5y is a partly sectional view of alboiler, and the dome shown in F ig. 4.

The water heating dome comprises a more or less conical corrugated shell 1, having openings 2 :from the outside portion of the,

Shell', t0 the inner portion t the shell 3 placed in' several different series. The outer andinner walls of the shell are separated farenough to permit the heating of a suitable quantity of water therein, which watermay be fed to an inlet pipe 4, or should it be necessary to use two inlet pipes, the plug may be removed, and another inlet pipe may be attached thereto. is out-let pipe 6.

The water heating dome is supported within the boiler 7, and below a conical bottom 8, a fine 9 extending from the top of the At the top of the dome conical bottom 8 through the top of the boiler.- The pipe 4 is yconnected to a suit.- able elbow 10, which in turn is connected to apipe' 11 passing through theA side of the boiler. This pipe 11 is connected to a T 12, and the latter is connected with-the coldwater feed pipe 13, and another pipe 14 leading into the lower part of the boiler to sup-' ply cold water therethrough. A burner 15 is suitably supported below the heating dome 1. 1t will be noted that the flame from the burner 15 willpass up through the.

openings in the heating dome 1, while some of it passes around the outside thereof, but

the larger quantity will pass th'rougl-1the'V ldome thus drawing a large quantity of water into contact with the llame'lv for the purpose of heating the water. It will also benoted that what flame therefrom doves pass outside of the dome 1, will strike the conical bottom 8, and since this is protected by the water within the boiler, the outside of the boiler will not become red li'ot,as is the case with boilers not so protected.

` Figs. 2, 4 and 5 show slight r4modifica tions of the invention. Fig. 2 shows theiwater dome 1 with side inlets 16 and 17 as is sometimes desired.v In Fig. 4, the dome 18 is provided with only four iame outlets 19,

said outlets being about one-third the distance below the top of the dome. This form is provided with a plug 5 and inlet `pipe4, same as dome shown in Fig. 1, and is con'- nected to the boiler in exactly the same way as shown. in Fig. 5.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, lnodificiv 'tions Within the scope of the claims being expressly reserved, is as follo\vs:

1. A water-heater comprising a hollow heating drum having an inner concave Wall and an outer convex Wall and providin a conical annular Water chamber there etween, 'inlet and outlet pipes connected therewith 'at the bottom yand top respectively, and said drum having a plurality of upwardly extendingl channels passingtransversely therethroug l.

2. A Water-heaterv comprising a hollow heating drum having an inner concave Well upwardly extending channels passing transy versely therethrough.

In testimony whereof I have hereunto sei my hand this 23' dey of August A. D. 1911, in the presence of the two subscribed Witnesses.

JOSEPH ANTONUCCIG.
